LINE D & D-1

Lines D and D-1 combine to receive the flow emanating from eight major freeway culverts and consolidate those into a single storm drain in Vine Street.

Line D-1 will have its upstream terminus at the 60 inch CSP culvert emerging from the Freeway at a point just east of Tokay Road. It will then run southeasterly, picking up the flows from another 5 freeway culverts and will deliver a combined 100 year flow of approximately 365 cfs to Line D at the intersection of Vine Street and the Freeway. The line will vary in size from 39 inch to 66 inch diameter reinforced concrete pipe located within the Freeway right of way.

Beginning within the Freeway right of way, about 800 feet south of Vine Street, Line D will convey the flow exiting the four 48 inch CSP freeway culverts northerly to junction with the flows from Line D-1. The 100 year flow of 325 cfs tributary to the upper end of D will be carried in a 2 foot wide, 4 foot deep trapezoidal channel to Vine Street. At this point, the 100 year combined flow will be conveyed down Vine Street in a RCP storm drain ranging in size from 66 inches to 81 inches.

The lower end of Line D will cross under Mission Trail and outlet its flow into the Lake below 1260 the foot elevation.

Before we get to Mission Trail we find several of these. Make you wonder how long ago these lines were cleaned out.

The County Flood Control needs to keep up on things as this line appears to have a couple of feet of sand emanating from it.
